The prayer is from the Hereafter, so when you enter it you leave the world.

From Ibnul Qayyim's The Path to Guidance, Chapter Nine, pp 89-92

(1) That Allaah, the Exalted, wipes away sins by the five prayers.

(2) That the five prayers are an expiation for what occurs between them, if major sins are avoided.

(3) That sins burn and destroy a person, and thus it is necessary to extinguish that with the prayers.

(4) That the Muslim reaches the level of the truthful and the martyrs on account of his prayers, charity and fasting.

(5) The superiority of prayer*2 over other actions.

(6) That Allaah, the Exalted, bestowed a favor upon that Companion by entering him into Paradise before his brother who died as a martyr because he prayed more than he.

(7) That the prayer is light which illuminates the path of the servant in this world and the Hereafter.

(8) That an abundance of prostrations and prayers is the way to accompany the Messenger (sallallaahu 'alaihi wa sallam) in Paradise.

(9) That a two-rak'ah prayer is more loved by the dead person than the world and whatever is in it.

(10) That emptying the heart for Allaah in the prayer puts a person in the same condition as the day when his mother gave birth to him...
